a table shows the cost (in cents) of producing and distributing each coin for the years 2007 and 2014
which coin has a cost in 2014 that is less than 0.95 times the cost in 2007
2007. 2014
quarter. 9.78. 8.95
dime. 4.09. 3.91
nickel. 9.53. 8.09
penny. 1.67. 1.66
The dime has a cost in 2014 that is less than 0.95 times the cost in 2007.
To solve this problem by finding out the ratio. We can solve this problem by following a few steps.
According to the question, the cost in 2014 is less than 0.95 times the cost in 2007.
So the ratio is 1: 0.95. Which can be written as, 1/ 0.95 = 100/95 = 20/19 = 20: 19.
Now, we have to find among all those coins which follow the trend of 20: 19.
For the quarter, the ratio is 9.78: 8.95 = 9.78 / 8.95 ≠ 20 : 19For the dime, the ratio is 4.09: 3.91 = 4.09/3.91 ≈20: 19For the nickel, the ratio is = 9.53: 8.09= 9.53. 8.09 ≠ 20: 19For the penny, the ratio is = 1.67: 1.66 = 1.67/1.66 ≠ 20: 19Here only the price of a dime has declined 0.95 times.

Make sure to show your work when answering the question. The insurance company pays the full cost of 3,900 prescriptions claims out of 4,500 prescriptions claims submitted. What is the rate of the claims paid expressed as a percent? Round to two decimal places.
The rate of the claims paid expressed as a percent is 86.67%.
Out of the 4,500 prescription claim submissions, it has been stated that the insurance company covers 3,900 prescription claims in full.
We must determine what percentage of 4,500 is 3,900 in order to solve the presented problem.
Percent of the claims paid = 3,900 / 4,500 x 100
Percent of the claims paid = 0.8666666 × 100
Percent of the claims paid 86.66666%
Percent of the claims paid = 86.67%
As a result, 86.67% would be the rate of claims paid represented as a percentage.

The ratio of 2 nickels to 27 dimes is 27.
What is ratio?A ratio in mathematics demonstrates how many times one number is contained in another. For instance, the ratio of oranges to lemons in a dish of fruit is eight to six if there are eight oranges and six lemons present. Similarly, the ratio of oranges to the total amount of fruit is 8:14 while that of lemons to oranges is 6:8. A ratio is an ordered pair of numbers a and b, expressed as a / b, where b is not equal to 0. A percentage is an equation in which two ratios are made equal to one another. For instance, you could express the ratio as 1: 3 (one boy to three females), meaning that one in four of the population is male.

The equation of the quadratic equation is P(x) = x² + 23/4x - 21/4
What are quadratic equations?Quadratic equations are second-order polynomial equations and they have the form y = ax^2 + bx + c or y = a(x - h)^2 + k
How to determine the quadratic equation?The given parameters are
Zeros = -7 and 3/4
The sum of multiplicities of the quadratic equation must be equal to the degree.
This means that the multiplicity of the zeros -7 and 3/4 is 1
The equation of the quadratic equation is then calculated as
P(x) = (x - zero)^ multiplicity
So, we have
P(x) = (x + 7)(x -3/4)
Expand
P(x) = x² + 7x - 3/4x - 21/4
This gives
P(x) = x² + 23/4x - 21/4
Hence, the equation is P(x) = x² + 23/4x - 21/4

What is probability?Simply put, the probability is the likelihood that something will occur. When we don't know how an event will turn out, we can discuss the likelihood or likelihood of various outcomes. Statistics is the study of events that follow a probability distribution. The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a proposition is true. An event's probability is a number between 0 and 1, where, roughly speaking, 0 denotes the event's impossibility and 1 denotes certainty.So, the probability to get all questions correct:
Probability formula: P(E) = Favourable outcomes/Total outcomes
The number of questions is 5.The options for each question are 4. Possible answers are 1.Then,
Favourable events = 1 × 5 = 5Total events = 3 × 5 = 15Now, find the probability by putting the values as follows:

○ C. (x+3)² + (y−4)² = 9
OD. (x-3)²+(y+4)² =
Answer:
B. (x − 3)² + (y+4)² = 81
Step-by-step explanation:
If a circle has center located at (a, b) and radius of r, the equation of this circle is
(x - a)² + (y-b)² = r²
We have a = 3, b = -4 and r = 9
So equation is
(x - 3)² + y - (-4))² = 9²
==> (x − 3)² + (y+4)² = 81
Write the equation of the line with the given information. Through (-1, -1) parallel to h(x)=-1+10
The equation of a line that passes through (-1, -1) and parallel to h(x) = -1x + 10 is y = -x -2
How to find equation of a line?The line passes through (-1, -1) and it is parallel to h(x) = -1x + 10
When lines are parallel, the slopes are the same.
Therefore, the equation of a line that passes through (-1, -1) and parallel to h(x) = -1x + 10 can be calculated as follows:
Hence,
y = mx + b
where
m = slopeb = y-interceptTherefore, let's find the y-intercept using (-1, -1)
y = -x + b
-1 = -(-1) + b
b = -1 - 1
b = -2

An expression is a set of term combined using the operators +, - /
From the option given
8+ x - 7 this can be further expressed as
8 + x - 7
x + 8 - 7
x - 1
The only expression in the option are x - 1, and 5
